假设 V 是一个接近无穷大的衰减电势。让我们用 NJ V) 表示 H=-A+ V 低于 -E 的特征值的数量。 N,,(V) 的有限性(或无穷大)由 V 在无穷远处的衰减率决定(参见 Reed-Simon [4, X111.31)。事实上,如果 V (x) B-c/~ xI*+~ 则 N,(V)< co,而 N,(V)= cc 对于 V (x)<-c/\x~*~‘。对于边界情况 V (x)-c/lx12 甚至有 N,,(V)< CO (resp.= co) if CC(d--2)‘) 其中 d 是空间维度。
Suppose V is a potential decaying near infinity. Let us denote by NJ V) the number of eigenvalues of H=-A+ V below-E. The finiteness (resp. infiniteness) of N,,(V) is determined by the rate of decay of V at infinity (see Reed-Simon [4, X111. 31) In fact, N,(V)< co if V (x) B-c/~ xI*+~, while N,(V)= cc for V (x)<-c/\x~*~‘. For the borderline case V (x)-c/lx12 one even has that N,,(V)< CO (resp.= co) if CC(d--2)‘) where d is the spatial dimension.
